Whatever pets you have, always take the time to clean their food and water containers properly and regularly (preferably daily). This is really important for their health, particularly for birds, but for any animal a build up of bacteria (which they are then consuming whenever they eat or drink) can make them really ill, sometimes even fatally. Use a small animal or bird safe disinfectant for scrubbing food bowls, water bowls and water bottles and then rinse well afterwards (food bowls will need drying too). Bottle brushes are very useful for getting the slime and grime out of the tricky to reach parts of a water bottle. A scourer or sponge, or even kitchen towel is often enough for bowls if they are done regularly enough. Water bottles should be taken completely apart regularly so that the spout can be cleaned as well.
